[0002] Linear lights, as one of the common LED lamps, are widely used in large spaces such as shopping malls, workshops or offices. They emit light through linear light strips, thus adapting to the long strips of light in the lighting space.

[0003] Existing linear lights generally include a housing, an end cover, and a light module, wherein a mounting cavity is formed between the housing and the end cover, and the light module is mounted in the mounting cavity. In some linear lights, a light-transmitting plate or light-transmitting cover is also provided on the housing. These linear lights generally have the following defects: (1) The end cover is a solid end cover. When the light module is lit, the dark area on the end cover surface causes uneven light mixing of the entire lamp. This is more obvious when multiple lamps are spliced ​​together. (2) Figure 1 As shown, since the light cover is installed above the lamp body, it is easy to collapse when the light cover is subjected to force, or the light cover may be separated from the lamp body; (3) light leakage occurs in the non-light-transmitting area, resulting in obvious light loss, and the light efficiency of the entire lamp cannot be effectively improved.

[0004] The prior art discloses a linear lamp, comprising a long strip lamp housing, two end covers, a flexible circuit board, a terminal and a light-transmitting cover. A mating portion is provided at both ends of the lamp housing, and a buckle portion for clamping with the mating portion is provided on each end cover. A mounting slot is also formed on the side of the end cover facing the lamp cavity; the light-transmitting cover is provided in the lamp slot and cooperates with the lamp slot to form a lamp cavity. When assembling the linear lamp, one end of the terminal can be welded to the flexible circuit board first, and then the terminal can be clamped into the mounting slot of the end cover to fix the terminal.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0062] Example 1

[0063] refer to Figure 2-Figure 6 The present embodiment provides a linear light 100, which can be used in outdoor places such as supermarkets, offices, workshops, gas stations, and parking lots. The linear light 100 includes a lamp body 1, a light source assembly 2, a light-transmitting cover 3, and an end cover 4. Among them, the lamp body 1 serves as the main frame of the linear light 100, and includes a base 11 and a support seat 12 for supporting and connecting the light-transmitting cover 3. The support seat 12 is fixedly mounted on both sides of the base 11, and a receiving cavity 10 is formed between the support seats 12 on both sides and the base 11, and the receiving cavity 10 is used to install the light source assembly 2 and other optical components. The base 11 has a mounting plane 110, and the direction perpendicular to the mounting plane 110 is the first direction L1. The support seat 12 extends a first connecting arm 121 in the first direction L1, and a first groove body 1211 is provided on the first connecting arm 121.

[0064] The light source assembly 2 is fixedly mounted on the base 11 . Specifically, the light source assembly 2 is entirely laid flat on the mounting plane 110 .

[0065] The light-transmitting cover 3 is a light-emitting component of the linear light 100. The light-transmitting cover 3 includes a cover body 31, which surrounds a light-transmitting cavity 30. The light-transmitting cavity 30 has a light outlet 32, which is used to receive light emitted from the light source assembly 2. The light-transmitting cavity 30 is interconnected with the accommodating cavity 10. The cover body 31 extends toward the light-transmitting cavity 30 at the end 311 to form a protrusion 312, which is engaged and connected in the first groove 1211, so that the light-transmitting cover 3 is engaged and fixed above the lamp body 1.

[0066] The end cap 4 includes a light-transmitting portion 41 and a light-shielding portion 42, wherein the light-shielding portion 42 is also referred to as a non-light-transmitting portion. The end cap 4 is fixedly connected to the end surface 120 of the lamp body 1 and the light-transmitting cover 3. The direction perpendicular to the end surface 120 is the second direction L2. Along the second direction L2, the end cap 4 covers the light-transmitting cavity 30 and the accommodating cavity 10 respectively.

[0067] The light emitted by the light source assembly 2 enters the light-transmitting cavity 30 through the light outlet 32, and then exits from the light-transmitting cover 3 and the light-transmitting portion 41 of the end cover 4; at this time, since the lamp body 1 is located at the end surface 120 of the accommodating cavity 10 and is shielded by the light-shielding portion 42 of the end cover 4, the light will not escape from the bottom of the lamp body, effectively reducing light loss and avoiding light leakage. The light is emitted through the light-transmitting cover 3 and the light-transmitting portions 41 at both ends, which can clearly define the light-emitting area and effectively mix the emitted light, thereby improving the light efficiency utilization rate.

[0068] exist Figure 5 Based on reference Figure 6In the linear lamp 100 of the present embodiment, the first slot body 1211 of the lamp body 1 has a first connecting arm 121 that is recessed toward the accommodating cavity 10, and the first slot body 1211 is provided with a slot body bottom surface 1212 that is inclined downward, that is, the slot body bottom surface 1212 of the first slot body 1211 is not parallel to the horizontal plane. In this way, on the one hand, the protrusion 312 can be guided to obliquely enter the first slot body 1211 and support the light-transmitting cover 3 above; on the other hand, the protrusion 312 of the light-transmitting cover 3 can be prevented from slipping off the first slot body 1211, causing the light-transmitting cover 3 to separate from the lamp body 1 and then collapse. Specifically, there is an angle θ between the slot body bottom surface 1212 and the horizontal plane S, and the angle θ is any value between 5°-10°. Correspondingly, there is an angle α between the slot body bottom surface 1212 and the slot body side wall surface 1213 of the first slot body 1211, α=90-θ. In some embodiments, θ is 5° and α is 85°.

[0069] In addition, the first connecting arm 121 is further provided with a hook 1213 above the first slot 1211, and the hook 1213 and the bottom surface 1212 surround the first slot 1211. After the protrusion 312 is inserted into the first slot 1211, the surface of the protrusion 312 abuts against the bottom surface 1212 and the hook 1213 respectively, which can further prevent the protrusion 312 from being loosened and separated from the first slot 1211.

[0070] Continue to refer Figure 5 and Figure 6 The support seat 12 is provided with a first buffer portion 124 near the first connecting arm 121. The first buffer portion 124 is a hollow cavity structure, and the outer side wall of the first buffer portion 124 is a serrated structure. The lamp body 1 can be formed by stamping a metal profile, such as an aluminum profile or a steel plate. When the lamp body 1 is squeezed by an external force, such as the light-transmitting cover 3 pressing the lamp body 1 in the first direction L1, the first buffer portion 124 will be elastically deformed and have a buffering effect of absorbing the external force. After the external force is removed, the hollow cavity of the first buffer portion 124 together with the serrated outer side wall will rebound to its original state.

[0071] It should be noted that, in the present embodiment, the light-transmitting portion 41 and the light-shielding portion 42 of the end cap 4 are integrally injection-molded, wherein the injection molding material used for the light-transmitting portion 41 is a mixture of transparent PC (polycarbonate) and an optical diffuser, and the injection molding material used for the light-shielding portion 42 is a non-transparent PC, such as a mixture of polycarbonate and titanium dioxide, and the two injection molding materials are integrally injection-molded by a two-color injection molding machine to obtain the end cap 4, and the overall structure of the end cap 4 is firm and not loose, and can be correspondingly matched to cover the light-transmitting cavity 30 and the accommodating cavity 10. In other embodiments, the light-transmitting portion 41 and the light-shielding portion 42 can also be separately injection-molded first, and then the light-transmitting portion 41 and the light-shielding portion 42 are fixedly connected together by bonding or clamping, and the entire end cap 4 is installed on the end faces of the lamp body 1 and the light-transmitting cover 4. In some embodiments, when the light-transmitting portion 41 and the light-shielding portion 42 are integrally injection molded, the light-transmitting portion 41 may be provided with a snap-fitting groove according to the designed mold, and correspondingly, the light-shielding portion 42 may be provided with a snap-fitting boss, which snaps into the snap-fitting groove, and can further ensure the tightness of the connection between the light-transmitting portion 41 and the light-shielding portion 42.

[0072] In some embodiments, the light-transmitting cover 3 is injection-molded using an injection molding material of transparent PC (polycarbonate) and an optical diffuser, wherein the cover body 31 is in a U-shaped structure, and the protrusion 312 is formed by the end 311 of the cover body 31 extending obliquely downward inward. In some embodiments, the cover body 31 may also be in an arc, semicircular or V-shaped structure.

[0073] Further references Figure 4 After the U-shaped cover 31 is installed above the lamp body 1, the light emitted by the light source assembly 2 is emitted from five surfaces, namely, three surfaces D1, D2 and D3 of the cover 31 and two light-transmitting surfaces (light-transmitting surfaces of the light-transmitting portion 41) D4 and D5 of the end cap 4. In some embodiments, the height of the light-transmitting portion 41 is the same as the height of the light-transmitting cavity 30, which can ensure that the light is evenly mixed in the light-transmitting cavity 30 and then emitted through the above five light-emitting surfaces.

[0074] In the settings of the light source components, such as Figure 8 As shown, the light source assembly 2 of this embodiment includes a substrate 21, a light-emitting element 22 and a lens 23, wherein the substrate 21 is an aluminum substrate or a ceramic substrate, the substrate 21 is embedded and mounted on the mounting position 111 of the base 11, and the bottom of the substrate 21 is tightly connected to the mounting plane 110. The light-emitting element 22 is an LED lamp bead, and the light-emitting element 22 is evenly attached to the substrate 21 by SMD patch method or COB welding method. The light-emitting element 22 has a light-emitting center 221 and a light-emitting plane 222. The lens 23 covers the light-emitting element 22. In this embodiment, each light-emitting element 22 corresponds to a lens 23. The lens 23 is a divergent light distribution lens, which can reduce the focusing, so as to accurately control the light of the light-emitting element 22.

[0075] The linear light of this embodiment optimizes the light emitting system. Specifically, along the first direction L1, there is a first light emitting distance A between the light emitting plane 222 and the first light incident surface 301 of the cover body 31, and the first light emitting distance A has a relationship: A≥1.2L;

[0076] Along the second direction L2, a second light emitting distance B exists between the light emitting center 221 of the light emitting element 22 closest to the end of the substrate 21 and the second light incident surface 302 of the cover 31, and the second light emitting distance B has a relationship: B≤0.6L.

[0077] Wherein, L is the distance between the luminous centers of two adjacent elements.

[0078] In addition, the first connection 401 between the light-transmitting portion 41 and the light-transmitting cover 3 and the second connection 402 between the light-shielding portion 42 and the lamp body 1 are filled with reflective adhesive. On the one hand, the reflective adhesive can make the components tightly connected so that light cannot escape; on the other hand, since the reflective adhesive has a reflective effect, the light can be reflected back to the light-transmitting cavity and then emitted from the cover body and the light-transmitting portion.

[0079] Furthermore, the support base 12 extends a second connecting arm 122 away from the first connecting arm 121, and the second connecting arm 122 continues to extend outward to form a base 123, and a second slot 1221 is formed between the base 123 and the support base 12. The support base 12 is further provided with a second buffer portion 125 near the second slot 1221.

[0080] In some embodiments, the linear light 100 further includes a bracket 5 and a connecting piece 6. The bracket 5 is clamped to the second slot 1221, and the bracket 5 is fixedly mounted on the external mounting base. During the clamping process between the bracket 5 and the second slot 1221, the second buffer portion 125 can also be elastically deformed so that the second slot 1221 can accommodate the clamping block of the bracket 5. After the installation is completed, the second buffer portion 125 returns to the initial state.

[0081] The inside of the wiring member 6 is electrically connected to the light source assembly 2. In addition, the wiring member 6 also fills the gap between the end cap 4 and the lamp body 1 to play a waterproof and dustproof role. In some embodiments, the end cap 4 and the lamp body 1 are also respectively provided with step structures to limit and fix the position of the wiring member 6 to prevent it from loosening from the end cap 4 and the lamp body 1.

[0082] In order to improve the connection reliability between the end cap 4 and the lamp body 2, the end cap 4 is provided with a first screw hole 43, and correspondingly, the lamp body 1 is provided with a second screw hole 13. The fastener 7, such as a screw, passes through the first screw hole 43 and is locked in the second screw hole 13. In some embodiments, there are four first screw holes 43 provided in the end cap 4; wherein the two upper first screw holes 43 are provided at the junction of the light-transmitting portion 41 and the light-shielding portion 42; and the two lower first screw holes 43 are close to the lower end of the light-shielding portion 42. The second screw holes 13 correspond to the first screw holes 43. Therefore, there are also four second screw holes 13 provided in the lamp body 1; wherein the two upper second screw holes 13 are provided above the first buffer portion 124, but the two second screw holes 13 are not connected to the first buffer portion 124; and the two lower second screw holes 13 are provided above the second buffer portion 125, and the two second screw holes 13 are connected to the second buffer portion 125. On the one hand, the first buffer portion 124 and the second buffer portion 125 can produce a buffering effect by elastic deformation when the lamp body 1 is squeezed by an external force; on the other hand, the first buffer portion 124 and the second buffer portion 125 are both hollow, which can save part of the metal material of the lamp body, reduce production costs, and reduce the weight of the lamp body 1, meeting the lightweight application requirements of linear lights.

[0083] In the linear lamp provided in this embodiment, the light-transmitting portion of the end cap covers the light-transmitting cavity of the light-transmitting cover in the second direction, and the light-shielding portion covers the accommodating cavity of the lamp body in the second direction, so that the light can be emitted evenly, and the light loss is reduced, and the light-emitting efficiency of the whole lamp is improved. The light-transmitting cover is connected to the first groove body through the protrusion, and then installed on the support seat of the lamp body, which can ensure the structural strength of the whole lamp and improve the safety of the product.

[0084] Example 2

[0085] exist Figure 8 Based on reference Fig. 9 , this embodiment optimizes the structural design of the line light. In the line light of this embodiment, 48 light emitting elements 22 are evenly attached on a 1m substrate 21. The distance L between the light emitting centers of adjacent light emitting elements 22 is: 1000mm / 48≈20.8mm.

[0086] In addition, the first light emission distance A is 1.2 times of L, that is, A=1.2L; the second light emission distance B is 0.6 times, that is, B=0.6L. For the description of the first light emission distance A and the second light emission distance B, please refer to Example 1, which will not be repeated here.

[0087] When the first light emitting distance A and the second light emitting distance B have different relationships with the distance L between adjacent light emitting centers, the forward illuminance distribution of the linear light is also different. Fig. 9 And Table 1, the simulation test results are as follows:

[0088] (1) When A = 1.2L, B = 0.6L, the forward illumination uniformity of the line light is relatively uniform, and no bright or dark mark can be seen between the two light sources;

[0089] (2) When A = 1.0L, B = 0.5L, the uniformity of the forward illumination of the line light is average, and there is a slight bright and dark mark between the two light sources;

[0090] (3) When A = 0.8L and B = 0.4L, the uniformity of the forward illumination of the line light is poor, and regular bright and dark marks appear between the two light sources.

[0091] Table 1 Test results of frontal illumination under different relationships between A, B and L

[0092]

[0093] Based on the above design parameters, the linear light of this embodiment adopts the golden ratio to set the spacing between the light-emitting elements, as well as the first light-emitting distance A and the second light-emitting distance B. The forward illumination uniformity of the linear light is relatively uniform, and no bright or dark marks can be seen between two adjacent light sources.

[0094] In the linear lamp of the present embodiment, the material of the light-transmitting cover is transparent PC (polycarbonate) + optical diffuser, and the light-transmitting part of the end cover also adopts the same material as the light-transmitting cover, so that the transmittance and haze of the light-transmitting part are consistent with those of the light-transmitting cover; and the connection between the end cover, the light-transmitting cover and the lamp body is filled with reflective adhesive, so that the secondary reflected light is evenly transitioned at the connection, ensuring that the five sides of the whole lamp (D1, D2, D3 of the light-transmitting cover, and D4 and D5 of the light-transmitting part of the end cover) emit light evenly.

[0095] Example 3

[0096] like Fig.10 As shown, this embodiment provides a lighting system 200, which is assembled using the linear lights 100 of Embodiment 1 or Embodiment 2.
